文摘
- •
We used electrodeposited copper micro-cubes as reductants for preparing Ag nanostructures (nanorods, nanosheets), that is a 0 dimension to 2 dimension (2D) process.
- •
Cu2O were identified as intermediate products of the redox reaction by XRD.
- •
Agglomerates on the cubes and reductants escaped from them acted as growth positions for anisotropic growth (nanoplates).
- •
Oriented attachment of nanoparticles determines the shapes of Ag nanostructures, such as nanonets, nanoplates, nanosheets.
- •
Reductant nanoparticles absorb on the edges of nanoplates improve their growth.
